That was not the only tool available. But tariffs are also not consistent with free market capitalism. To think otherwise is muddled thinking.
As far as your response that my thinking is muddled look again to the quote by Frank Lloyd Wright. He is exactly correct.
Mr Wright may be correct, but that has nothing to do with the fact that it is muddled thinking to claim to be for free market capitalism and free market labor and labor unions.
Why do you say that? In what way is a labor union not free market labor? What's the difference between a union and a corporation?
Suppose a bunch of autoworkers were to form a corporation that's in the business of supplying contract labor to other corporations, and it contracts with Ford to supply autoworkers, and it sends Ford its own shareholder/owner/employees to build Fords, and Ford pays them, and it, the amount their corporation contracted for on their behalf. Then in what substantive way is that different from the UAW? And in what substantive way is that different from Kelly Services, Inc.?
